The Political Nature of "Religion"

The Sacred Is the Profane collects nine essays by William Arnal and Russell Mc Cutcheon that advance current scholarly debates on secularism-debates. The essays return, again and again, to the question of what "religion"—word and concept—accomplishes, now, for those who employ it, whether at the popular, political, or scholarly level. The focus here is on the efficacy, costs, and the tactical work carried out by dividing the world between religious and political, church and state, sacred and profane.
